Fig. 3From: Leishmania tarentolae: a vaccine platform to target dendritic cells and a surrogate pathogen for next generation vaccine research in leishmaniases and viral infectionsUse of microbial vectors in vaccination against viruses and other pathogens. A gene coding for an antigen is selected from a pathogen and cloned for its expression into a microbial vehicle (1). Different types of expression could be exploited (2). The selected microbial vehicle is then used for the immunization of the host (3). GM, Genetically modified, WT, wild typeBack to article page
